CVE-2026-90306

CVE-2026-90306 affects the Linux kernel on ARM architectures. The vulnerability resides in the hw_breakpoint_cfi_handler() stub, which was unconditionally claiming breakpoint type 0x03 (ARM_ENTRY_CFI_BREAKPOINT) even when CFI (Control Flow Integrity) was not actively instrumented in the kernel. T...

CVE-2026-90305

CVE-2026-90305 affects the Linux kernel on ARM when PREEMPT_RT is enabled. The root cause is that commit c6e61c06d606 enabled PREEMPT_RT on ARM without selecting HAVE_POSIX_CPU_TIMERS_TASK_WORK , leaving CPU timers to expire in hard IRQ context . On PREEMPT_RT, this causes run_posix_cpu_timers() ...
